...HIGH RIP CURRENT RISK IN EFFECT THROUGH FRIDAY EVENING...

The National Weather Service in Miami has issued a High Surf
Advisory, which is in effect until 8 PM EDT Friday. A High Rip
Current Risk has also been issued. This High Rip Current Risk is
in effect through Friday evening. 

* WAVES AND SURF...Large breaking waves associated with swell from
  Hurricane Florence will increase to heights of 7 to 9 feet later
  today, especially over northern portions of Palm Beach County.

* TIMING...Highest threat of high surf and rip currents is this
  afternoon through tonight.

* IMPACTS...Strong rip currents will be hazardous to those in the
  surf zone along Palm Beach County beaches. In addition, rough
  surf from large, breaking waves will be hazardous to swimmers
  and could lead to significant beach erosion.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A High Surf Advisory means that high surf will affect beaches in
the advisory area, producing localized beach erosion and
dangerous swimming conditions.

There is a high risk of rip currents.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins, jetties
and piers. Heed the advice of lifeguards, beach patrol flags and
signs.

Swim near a lifeguard. If caught in a rip current, relax and
float. Don't swim against the current. If able, swim in a
direction following the shoreline. If unable to escape, face the
shore and call or wave for help.
